' 'MEANS non 'SETTING',Nonsanaaaatn waren CRYSTALS.

To all 'w zom t may concern e Be it known that l', Josnrri GoT'rLrEB, a citizen of the United States, and resident of the boroughof Brooklyn, county of Kings, State of vYew York, have invented certain new and useful lmprovements in Means for Setting Nonbreakable lVatch Crystals, 'of which the following is the specification.

The use of glass as a watch-crystal or as a means of covering the face of'a watch is not entirely satisfactory'whenthe watch is submitted to extraordinary service.' This is particularly true of crystals for wrist or military watches, 'and means Vhavebee'n devised lfor guarding Aor protecting the crys-y tal, but such means are not entirely satis factory for the reason that they cover" the face of the watchto a certain extentY and make its observation difficult, further they add to the thickness 4or bulk ofthe watch. Non-breakable watch-crystals have been `produced.V These crystals, so-called, are

made' of a particularly'hardand clear 'celluloid -or similar material. The nature of f thismaterialis well understood and it is known that one of the principal objections to its use as a Vwatch crystalvis'the difficulty in securing it in the bezelof thewatch.

A Celluloidwatch-crystals are made flat or are cut from a sheet of suitable thin and clear Celluloid and musty therefore be dished Y or made concave-convex vbefore they can be secured to the bezelv and it Vhasl been found difficult and many times impossible f to give these non-breakable crystals a satisfactory shape by means ofthe fingers only.v Y. The device Vwhich l amabout todescribe is a 'mechanism' designedvfor the purpose of shaping non-breakable crystals and retain-Y ing them in the desired shape adjacent to a' bezel and then uponthe release of-the pressure applied in shaping the Acrystal Vit will attach itselfto thebezel.- y f l The device has thenfor its principal ob- Yject that of assisting in placing non-breakable crystals in watch Abezels and the confully set forth as the specification `proto 'for a comjplete` understanding Vof the struction and operation'of the device will be y gresses. y y, Y

' The following is what l consider agood *mea-ns: of carrying out my invention and the accompanying drawings should be referred speciication. w iich follows i922; 1 seriai ivatasis.

- Fie.' 5, is aireversedk plan viewof kthe 23 member shownin Fig. 4. 'f Y yFig; 6, a sectional View' of the member shown in Fig. l, and i Fig. 7, an elevation of the punch or de-A pressing inember.

Similar reference numerals indicate like parts in all the figures where they'A appear. Y lnFig. 1, letus consider that 1 indicates the floor, then 2`would indicate a table of a suitable size and elevated a`r convenient height from the floor. This table Q'my be,` iii;

independently yformed, that is, constructed only for thefuse' and accommodation of my device and if so I prefer that itsheight shouldbe'such as toallowLan operator vto observe the work vvwhile seated before the machine. Y 'e Y Secured yto the table Eby `means `of the screws and ter otherwise is a, base plate having extending 'lugs 5 and' pthrough trunnion or,` bearing perforated as shown by the dotted lines 10 inFig. 2.

"Forward of the yarm 7 yand formed integral therewith kis'a y cupped shape member 11 h'avingan inwardly projecting flan e 12 andit will be noted-that l produce a arge perforation 13 in the flange 12 and that'this f I' perforation lpasses quite through the bottom of the cu'p`11. slot 14 is produced in the arm? for apurposethat shall appear later." Piv'oted to-the' upwardly extendingv memv"ber 8 and to the trunnion or bearing therein is; anarm or lever 15 having a plurality ofdownwa'rd extensions 16 perforated to receivejthe pivot 17 by means of whichthe arm-or leverl isconnected to the upward extension 8. VAt thforward' end of the le- 5' ver 15 is a downwardly extending portion lhaving a perforation'orrecess 19 and a lug forined integral with the' underside of the yarm 15 receives a pivot 21' to which the operating rod 22 is attached. l

The rod 22 is made separable and adjust-- able and the two positions of this rod are secured together by means of screws 23 and 24. The lower sect-ion ofthe rod 22 is pivoted to a foot lever 25 at the outer end of which is a step 26. l

The inner end of the foot lever 25 is pivoted at 27 to a floor bracket having parallel arms of different lengths. The arm 28 extends above the pivot 27 to a considerable degree. and the opposite arm 29 extends upward only sufficient to provide a support for the pivot 27. A foot piece 30 is perforated to receive screws 31 which secure the footpiece and iioor bracket to the floor or other convenient support.

The spring 32 sec-uredto the upwardly extending member 28 and also to the lever 25` tends to retain the lever 25 elevated and by so doing also elevates the arm or lever 15 and parts attached thereto.

The member 44 which I call a die and which is shown in` detail in Figs. 4, 5 and 6 is received in the cup l1 and rests upon theiiange 12. This die member has an interior. shoulder 33 and a hollowed portion 36 on the other side and it is to be-noted that the diameters of the shoulders 33 and 34 differ. The member which I call a punch, shown in elevation in Fig. 7 has a body 38 and an upward projection 39. The lower face of the body 38 is slightly convex as shown at 40.

:I provide a plurality of these so-called punches and dies, but the outer diameter of all of the dies is the same and the diameter ofthe projection 39 is in each instance the same.

I will now describe the operation of my device using thesame reference characters, so that the function of each part may be 1 readily understood. f

The levers 15 and 25 being elevated, a die of a .suitable size is selected and placed in the cup 11. The underside ofthe die rests upon the flai'ige 12 and it will be understood that the flange and the adjacent face of the die should be free of obstructionso that the die may rest fairly upon the flange 12.

A punch approximately the diameter of the recess 34 or 36 of the die, though somewhat smaller than the recess, is next selected and its upwardvprojection inserted Yinto the socket of perforation 19. The crystal is next placed upon theshoulder 33 vor 35 Y and the beviel arranged over the crystal and probably supported upon the die exterior to the shoulder just -mentioned New a pressure of' the footv of 'the operator upon the step 26 will depress the punch and will force the crystal downward into the recess 34 or 36 and the edges of the crystal will then project upward through' the bezel,

The bezel is retained in position by the fingers of the operator and when the pressure of the foot is released the crystal will expand into the crystal receiving cut into the bezel, the whole operation taking butl an' exceedingly shortvspace of time.

The position of the bezel during the operation of setting a crystalis shown by the dotted lines B in F ig. 1.

As before mentioned I may provide a vplurality' of dies, but as all will be of approximately the same construction .having two operative faces, it is only necessary to showthe one as illustrated. It should, however, be understood that modifications may be made within the scope of the appended claims without Vdeparting from the principle or sacrificing the advantages of the invention.

Having carefully and fully described my invention, what l claim and desire to secure by Letters Patent is l. .A device for setting non-breakahle crystals including a die having recesses of various diameters in opposed faces thereof, shoulders on opposed faces of said die, and a punch adapted to operate into said die, the operating face of said punch being conveX. j

f 2. A device for setting non-breakable crystalscomprising a cup shaped member having an inwardly projecting flange and a kdie arranged therein, a lever over said cupA shaped memberand having a recess anda punch yarranged thereinand means for operating said punch into said die.

3. A device for settingv non-breakable crystals comprising a cup shaped member, an arm extending therefrom, an upward projection from said f arm and having a bearing, a lever pivoted to said bearing and having a recess, a punch in said recess and avmeans for depressing said punch toward and into said cap shaped member. c

4. A device for setting non-breakable crystals, comprising;- a cup shaped member and a die arranged therein,a projection from ksaid member and a bearing formed therein, an armpivoted in said bearing, aV

punch in said arm, in combination with means formoving said punch toward said cup shaped member, said means comprising a foot lever and a floor bracket, said floor bracket having an upward extension, to which said lever vis pivoted, a spring atltachedito the upper end of said extension and to said foot lever and an operating rod from said leverto said arm, all combined for joint operation, as and for the purpose' setA forth.
